PATENT; OFFICE NEW YORK, N. Y., A CORPORATION OF NEW YORK INTERMEDIATESUPPORT FOR VENETIAN BLIND TILT BAIIS Application filed May 6,

A Venetian blind usually consists of .a head rail adapted to be securedto the top of a window or other opening; and a depending tilt railpivotally mounted on the head rail and supporting a series of thin slatsin spaced apart relation to effect an angular tilting of the tilt railand slats, together with suitable means for raising the slats and controlling the tilting.

One of the salient objects of the invention is to design a one pieceintermediate support which is pivotally connected to the tilt rail atsubstantially the center of the cross section or horizontal axis ofrotation thereof, so as to ermit free angular tilting of the tilt railand slat members throu h a complete half turn or 180 degrees, to e 'ecta complete closing of the blind.

A further object is to provide a one piece support of rigidconstruction, which is economical to manufacture, which can be easilyand quickly installed, and which permits the tilt rail being made up oftwo or more sections, thereby effecting a material saving in cost of thetilt rail.

The above and other objects will appear as the specification progresses,reference being had to the accompanying drawing in which I have shownthe preferred embodiment of so my invention, and in which like referencenumerals indicate like parts throughout the several views thereof.

In the drawing:

Fi 1 is a front elevation of a Venetian blin mounted in a window casingand showing my improved intermediate support in place thereon.

' Fig. 2 is an enlarged fragmentary front view of the tilt rail ilustrating'my support. Fig. 3 is an enlarged inverted plan view.

Fig. 4 is a section taken on the line 4-4 of Fig. 2, and showing thesupport and link, the tilt rail being omitted.

Fig. 5.. is a section taken on the line 5-5 of Fig. 3, also with thetilt bar omitted.

In blinds of large size it is necessary to provide one or moreintermediate supports on the tilt rail to prevent sagging, and insure"easy and correct operation, this interao mediate support further permitsthe tilt rail 1931. Serial No. 535,341.

proper being made up of two or more comparatively short pieces of stock,which is-of course an economical advantage, and also minimizes thepossibility of warping.

In the drawing, the numeral 5 indicates a window casement, having thehead rail 6'secured to the upper end thereof, and brackets 7 serve tohold it securely in position. Depending brackets 8 and 9 respectivelyare secured to the underside of the head rail, and a tilt rail 10 ispivotally mounted therein by means of pintles 11 which are mounted in,

,being punched to provide a central rib section 15, (see Fig. 3), themetal on the sides of the ribs being bent upwardly to form spaced apartWings 16, the upper ends 17 of which are bent at right angles, and in ahorizontal plane, and are provided with suitable openings to receiveconventional wood screws 18 for securing the end of the tilt railsections thereto, ample bearing is provided for the bottom of thesections, each of the legs 19 being provided with suitable opening forreceiving similar wood screws 20 as shown.

A horizontally disposed pin 21 is mounted in these vertically disposedwings at a point exactly in line with the axis of rotation of the tiltrail, and a link 22 is connected thereto, the upper end of said linkbeing shaped to form a hook 23 which is adapted to engage a screw eye 24which is anchored in the head rail directly above the support.

The means for tilting the mechanism is not shown in the accompanyingdrawing nor is the means for raising the slats, and it will beunderstood that these are of the conventional design and form no part ofthe present invention which is directed to the intermediate support forthe tilt bar.

From the foregoing-description it will be obvious that I have perfecteda very simple, ractical, uniform and economical one piece intermediatesupport for the tilt rails o Venetian blinds.

What I claim is 1. A one-piece bracket for connecting the inner ends ofVenetian blind tilt rail sections, and comprising a plate, opposedsections punched in the plate intermediate its Width, said sectionsbeing bent upwardly and lying in spaced apart relation, the upper endsbeing bent horizontally to overlap the upper face of the tilt rail, theedge sections of the plate being horizontally disposed and forming wingsadapted to be secured to the bottom face of said tilt rail.

2. A one-piece bracket for connecting the inner ends of Venetian blindtilt rail sections, and comprising a plate, opposed sections punched inthe plate intermediate its Width, said sections being bent upwardly inspaced apart relation with the upper ends bent to overlap the upper faceof the rail, the edges of the plate adprcent to said punched sectionsforming Wings for engaging the bottom face of the tilt rail, alongitudinally disposed pin mounted in the vertically disposed portionof said sections, and a link pivotally connected to said in and formedwith an open jaw for detacha le engagement with a support.

In testimony whereof I hereunto afiix my signature.

FRED J. BURNS.
